To all whom it may conccm:

Be it known that 1, JAMES TAYLOR, a citizen of the United States, and aresident of the city of New York, borough of Man hattan, in the countyand State of New York, have invented a new and Improved Lock for Motors,of which the following is full, clear, and exact description.

The present invention relates to new and useful improvements in devicesfor locking motor vehicles, and itpertains more particularly to amechanism adapted to render inoperative the fuel and ignition supplysystem of the motor of said vehicle.

It is one of the primary objects of the present invention to provide adevice whereby the supply of fuel to a carbureter of the internalcombustion motor may be entirely shut off, thus rendering the motorinoperative.

It is a further object of the invention'to provide means in combinationwith the fuel control :tor breaking the ignition circuit to furtherrender the motor inoperative.

It is a further object of the invention to provide a device whichincludes a looking mechanism constructed in such a manner that after itha once been opened, the key may be removeththe structure being such asto permit oil an automatic locking of the mechanism when moved to theinoperative position.

It is a still further object of the present invention to so construct adevice of this character that the same will be readily adaptable tomotor vehicles at present in use without materially changing theirmechanisms or designs.

With the above and other objects in view, reference is had to theaccompanying drawings, in which Figure 1 is a front elevation partlybroken away of a device constructed in ac cordance with the presentinvention;

Fig. 2 isa longitudinal. sectional view thereof;

Fig. 3 is a detail top plan view;

Fig. 4 is a sectionl View taken on the line itof Fig. 2, with theseveral parts in their locked position;

Fig. 5 is a similar view with the parts in their. open position; v

Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 2, withthe-parts of the locking mechanism in their locked position;

Fig. 7 is a similar View with, the parts in their open position;

Fig. 8 is a rear elevation or the device Referring more particularly tothe drawings, the. gas line of the motor is indicated by the referencecharacter 10, and mounted in said gas line 10, is a valve chamber 11.lhis valve chamber 11 has an inletpassage 13 and an outlet passage 12,and'has its bottom wall closed by means of a plug 1%, said plug servingto permit of access to the chamber 11 for the purpose of draining andcleaning the same. liteciprocatively mounted within the chamber 11, is apiston valve 15, and said piston valve is adapted to open the inlet 13to the outlet 12, or to close communication between the inlet and outletports depending upon its position in the chamber or casing 11.Projecting vertically from the casing 11 is a tubular member 16, andfitting in the upper end of said tubular member 16 is a flexible tubularmember 17, upon the upper end of which is secured another tubular member18.

Mounted upon the upper end of the tubular member 18 is the yokeextension 19 of a housing 20, said housing being circular in crosssectional form. Mounted in the hous ing 20 is a rotating member 21, andsaid rotating member is provided with thumb pieces 22, by means of whichit is grasped in order that it may be rotated.

Projecting from the rear face of the rotating member 21, is a pin 23 andpivotally connected to said pin 23, is a crank or lever 24. The lowerend of this crank or lever 24: is bifurcated as at 25, and mounted inthe bifurcated end 25 of said crank 24:, is a tubular member 26. Thistubular member 26 is connected to a flexible shaft 27, the lower end ofwhich is secured within a tubular member 28, which in turn is secured tothe valve member 15 by means of a bolt or the like 29. I

By this construction it will be noted that as the member 21 is rotatedwithin the housing 20, through the medium of the flexible sha t 27 andits several connections and the crank 24, the valve member 15 will bereciprocated in the valve chamber 11 to either open or close the outletport 12.

The rotating member 21 has a tubular extension 30 and mounted in saidtubular extension 30 is a lock 31, which look is adapted to be operatedby means of akey inserted into the keyhole slot 32. The keyhole slot 32is adapted to be protected from the -weather by means of, a cover plate.33, and

' ected into .a recess 41 through one of the Walls of the rotatingmember 21, to prevent rotary movement of the said member 21 in itsmounting." -This reciprocating member 40 .is rigidly mounted in ahousing 42, and

interposed between said housing and a cup 43, is a coil spring 44, whichcoil spring serves to maintain the reciprocating mem ber 40 in therecess 41 when the same are in register with each other. In order toposition the plunger 40 within the rotating member 21, a closing bolt 45is employed, said bolt having screw-threaded engagement with an openingin the top of the housing 20.

The lock 31 is adapted to actuate a cam member 46 and in its rotationsaid cam member 46 is adapted to engage the housing 42 to move thereciprocating member 40 out of the recess 41 to permit of a freemovement of the rotary member 21 within the housing 20. The housing 20is provided at opposite points on its interior with lugs 52 and 53, andcarried by the rotating member 21 in such position as to engage theselugs to limit the rotating movement of the member 21, is a projectingpin or lug 55.

The reference character 56 designates a rear closing plate for thehousing 20, and mounted as shown in Fig. 6 on said rear closing plate56, are two curved springs 57 and 58. These curved springs 57 and 58 areeach retained in position by means of a screw 59 and are positionedadjacent the lug 52 in such a manner that as the pin engages said lug52, it will pass between the springs 57 and 58 in contact therewith asshown in Fig. 7.

The screws 59 which secure the spring members 57 and 58 in position onthe rear closing plate 56, project through said closing plate 56 asindicated by the reference character 60 and provide the terminals orbinding posts for the wires of the igni tion circuit. 7

Assuming that the valve member 15 is in the position shown in Fig. 2 andthe several parts of the locking mechanism are in their securedpositions, the operation of the device is as follows:

The plate 33 is elevated and a key inserted into thekeyhole slot 32.Upon turningth'e key in the slot 32, the lock member 31 will be" rotatedand through the medium of the cam 46, the reciprocating member 40 willbe withdrawn from the recess 41 to the position which will permit of afree turn ing of the rotating member 21 within the housing 20. After.the reciprocating mem- Simultaneously with this operation, the

pin 55 passesbetween the springs 57 and 58 and completes the electricalcircuit in order that proper ignition may be had. After this operationtakes place, the key is rotated backwardly to a position where the camis moved to the position shown inFig. 4. in this position, however,owing tothe fact that the rotating member 21 has not been moved, thefree end of the reciprocating member 40 will engage the inner wall ofthe housing 20 and will not interfere with the proper rotation of themember 21.

When it is desired to lock thelnotor, it will only be necessary to graspthe thumb pieces 22, rotate the rotary member 21 anticlockwise until itreaches such a position that the end of the reciprocating member 40 willenter the recess 41 and hold all of the parts in their locked position.Simul taneously with this operation, the pin 55 will passfrom betweenthe springs 57 and 58, thus breaking the electrical circuit andrendering the ignition system of the motor inoperative. I i

It is to be understood that the terminals 60 of the wire 70 of theignition circuit may be suitably insulated in orderthat the properresults may be had.

While in the present instance the invention has been described aspertaining particularly to motors for motor vehicles, it is obvious thatthesame is capable of use in connection with fluid lines and electricalcircuits generally and is not. limited to: use

in controlling the supply of fuel and current r to internal combustionmotors.
